Multiple Criteria in IF Statement

Hi, Can you possible help me with the following?
The formula below needs to be combined to also included the following scenario when (B2,1)="J","J000",(LEFT(B2,2))&"00")

How can I combine logical tests to look at either scenario in one formula?

=IF(LEFT(B2,1)="H","H000",(LEFT(B2,2))&"00")
AND
=IF(LEFT(B2,1)="J","J000",(LEFT(B2,2))&"00")


PLEASE IGNORE THE REQUEST - I'VE FIGURED IT OUT!
